It is possible to skip a segment in the video
file by setting the In Frame to a point
following the Out Frame value.
18. Video Control
The channel Gobo control defines how the current layer will be ‘composed’ with the previous layers and the
playback options in each mode .The Digital Spot 7000 supports the following options:
Copy mode (0-17 DMX) : In this mode, the pixels of the layer are written on top of the previous layers.
Addition mode (20-37 DMX : In this mode, the pixel values of the current layer are added to the ones of
the previous layers. This means that “dark” pixels in the current layer image won’t alter the pixels
that are underneath while “light” pixel will saturate the image underneath.
Subtraction mode (40-47DMX) : In this mode, the pixel values of the current layer are subtracted from the pixel
value in the underlying layers. Dark pixel from the current layer won’t alter the pixel of
the layers underneath while light pixel will darken them.
Multiplication mode (60-77 DMX): In this mode, the pixels from the current layer will be multiplied by the pixels of
the underlying layers. For a pixel to appear bright in the output, the equivalent pixel of
the current layer and the underlying layer needs to be bright. If any of the layers has
a dark pixel, the result will be dark.
Minimum mode (80-97 DMX): This mode takes the pixel that is the darkest between the current layer and
the layer underneath
Maximum mode (100-117 DMX) : This mode takes the pixel that is the brightest between the current layer and
the layer underneath.
The playback options:
DMX value Playback option Meaning
0. Play forward continuously if dimmer >0 Plays the video segment from In Frame point to
Out Frame point, continuous looping. The dimmer
value has to be greater than 0.
1 Play forward once if dimmer >0 Plays the video segment from In Frame point to
Out Frame point and holds on the last frame.
The dimmer value has to be greater than 0.
2 Pause Stops playback of video file at the current playing
3
Play forward in continuous loop Plays the video segment from In frame point to Out
Frame point, looping continuously
frame
4 Play forward once Plays the video segment from In Frame point to Out
Frame point and holds on the last frame
